Searching for ultralight bosons with Josephson junction interferometry
Djuna Croon, Tanmay Kumar Poddar
Ultralight bosons sourced by macroscopic objects can generate long-range spin-independent and spin-dependent potentials that are accessible to precision interferometry. Such potent…
Searching for axions with quantum interferometry
Tanmay Kumar Poddar, Michael Spannowsky
Quantum phase measurements offer a complementary route to axion searches. We show that axion-photon interactions can imprint both Aharonov-Bohm (AB) and Berry phases in experimenta…
The COSMIC WISPers White Paper: The physics case for Weakly Interacting Slim Particles
Ariel Arza, Deniz Aybas, Shyam Balaji +124
Axions and other very weakly interacting slim particles (WISPs), with masses below 1 GeV, arise naturally in many extensions of the Standard Model of particle physics. In particula…
Searching for axions with time resolved pulsar polarimetry
Francesca Chadha-Day, Tanmay Kumar Poddar
Pulsars possess strong dipole magnetic fields that can source axion fields through the axion-photon interaction. Pulsars may therefore be surrounded by axion field configurations o…
Ultralight time-oscillating scalars from magnetized compact stars: electrophilic radiation and photon propagation effects
Tanmay kumar Poddar, Gaetano Lambiase
Ultralight scalars with electrophilic couplings to the time-dependent Goldreich-Julian charge density of magnetized compact stars can be radiated from their magnetospheres, contrib…
Photon-dark photon oscillation in M87 and Crab Nebula environments
Tanmay Kumar Poddar, Sourov Roy, Pratick Sarkar
Compact astrophysical systems such as neutron stars and black holes provide powerful laboratories for testing feebly coupled dark photons (DPs). We investigate light DPs kineticall…

Gaetano Lambiase, Tanmay Kumar Poddar, Luca Visinelli
We assess the effect of the Cosmic Neutrino Background (CB) on superradiant instabilities caused by an ultralight scalar field around spinning black holes (BHs). When the scalar…

We obtain novel constraints on new scalar fields interacting with Standard Model fermions through Lorentz-violating couplings, bridging searches for scalar particles and Lorentz-sy…
Constraining electromagnetic couplings of ultralight scalars from compact stars
Tanmay Kumar Poddar, Amol Dighe
If an ultralight scalar interacts with the electromagnetic fields of a compact rotating star, then a long-range scalar field is developed outside the star. The Coulomb-like profile…
Limits on dark matter, ultralight scalars, and cosmic neutrinos with gyroscope spin and precision clocks
Sara Rufrano Aliberti, Gaetano Lambiase, Tanmay Kumar Poddar
Dark matter (DM) within the solar system induces deviations in the geodetic drift of gyroscope spin due to its gravitational interaction. Assuming a constant DM density as a minima…

Francesco Grippa, Gaetano Lambiase, Tanmay Kumar Poddar
We investigate the effects of dark scalar- and vector-mediated interactions on dark matter admixed neutron stars, employing the two-fluid formalism. We adopt three different nuclea…

Gaetano Lambiase, Tanmay Kumar Poddar
An ultralight electrophilic scalar field can produce a long-range Yukawa-like spatial profile around a rotating, magnetized star when coupled to the constant number density of elec…

Gaetano Lambiase, Tanmay Kumar Poddar
The interaction of neutrinos with ultralight scalar and vector dark matter backgrounds induce a modification of the neutrino dispersion relation. The effects of this modification a…
